Hi Michael & Matthias, I just re-ran my build after the removal of the coreutils patch. The build went past coreutils with no problem. However it has then failed at clamav (1.4.0) with the message error: package `home v0.5.9` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.67.0 Either upgrade to rustc 1.70.0 or newer, or use cargo update -p home(a)0.5.9 --precise ver where `ver` is the latest version of `home` supporting rustc 1.67.0 Rust was reverted back to 1.67.0 due to problems with building ruby for aarch64 and riscv64. https://git.ipfire.org/?p=ipfire-2.x.git;a=commit;h=33ee3958de834f7eb686fb5b5daa56d511bb18e9 So until rust has the fix for building ruby for aarch64 and riscv64 then it looks like there needs to be a limit set to the version of rust-home to 0.5.3, which is the version that we have with rust-1.67.0 Unless of course I have not understood the root cause of this problem, which definitely could be the case. Regards, Adolf.
